[Pdns-users] CNAME record to an external domain

I'll be even more specific, as the problem is even more interesting.

We are talking about my dns server dns1.arctur.si (MASTER)

1) I have domain tehnodrvo.hr with external CNAME record:

tehnodrvo.hr 	CNAME 	tehnodrvo.dyndns.org

This IS resolvable, but on the SLAVE servers (also PDNS) I'm getting every 5 minutes this:

Error trying to retrieve/refresh 'tehnodrvo.hr': Query to '' for SOA of 'tehnodrvo.hr' produced a CNAME record


2) The other one, wich I was talking about in the first post (see also below) is urad.si with external CNAME record:

urad.si 	CNAME 	urad.blogspot.com

This one IS NOT resolvable, it returns NXDOMAIN.


Any help would really be aprichiated!

Kind regards, Marko Kobal.
